How to remove the added tag to the tagtextbox?

Hi! Im using the “TagAdded” event, and i have a check if the tag added is a valid phone number, and if the return is false i would like to make the tag to disappear when the user adds it.

Something like this:

  Private Sub TagTextBox2_TagAdded(sender As Object, e As TagTextBoxEventArgs) Handles TagTextBox2.TagAdded

if not e.Text.StartsWith(“+351”) then

‘don’t add the tag…

End if

End Sub

Thanks for the help guys!
